To find the fuse, look for the fuse box (inside the cabin) or the power box (in the engine compartment). First, disable the fuel system by removing the fuel pump fuse.Once you have your car battery on a bench, Connect the 9V battery to the car battery terminals before disconnecting the cables. If you don't want to buy a memory saver now, you can use a 9V battery instead. However, before disconnecting the terminals from the battery, you may want to use a memory saver to keep the computer memory alive and other electronic device settings (see the Saving Your Computer Memory box below). A simple inspection may help you quickly spot problems that can lead to battery problems.įor a better inspection, it is a good idea to disconnect the battery and check it on a bench or similar surface. Start a battery discharge diagnostic with a visual inspection. For example, you may forget to check the battery electrolyte level, check the terminals for corrosion or looseness, or make sure that the battery is held in place to prevent physical damage. Many times, problems with a battery that will not hold a charge can be traced to poor battery maintenance.
(Too much acid shortens the life of the battery more than too little.Instructions and tips for each of these tests are included below. It is best not to attempt to add acid to to replace the loss.
The sulfuric acid lost from the battery by an accidental overflow is probably a small enough amount as to be immaterial to the operation of the battery.Visually inspect any overfilled battery weekly for a month to see if there is any further overflow, and clean any overflow as described above if necessary.Finally, clean anything that the overflow contacted with a rag dampened with window cleaner. You do not want to take a chance that the residue of acid will get on something else. Pour the water down a drain, being careful not to splash the water around. After the job is done, discard the rinsed-out rag or paper towel in the regular trash.Wear gloves-don't get the water on your hands. Rinse the rag or paper towel in a pail of water. Do not let the rag or paper towels get wet enough to drip on other parts of the car or anything. Clean it with a rag or with paper towels by wiping away from the ports.

If there was an overflow onto the top of the battery, remember that the overflow is acidic - do not let it touch your skin or clothing. If you accidentally overfilled the battery but there is no overflow onto the top surface of the battery, the best thing to do is just to stop filling and let it be.

Ensure all areas are clean and free from dirt or debris, then place cleaned port covers back onto the battery. (This will also reset the car's electronics.) Make sure the terminals are completely dry before replacing them on the battery. The hot water will melt away the corrosion, leaving a clean surface.
Again, wet the rag and wipe, do not soak the battery with baking soda. Heavy corrosion can be cleaned with a paste of baking soda and water.Paper towels can be used as long as you replace them before they disintegrate to bits. Spray the cleaner on your rag - not on the battery itself - and wipe away any dirt. For general cleaning of road grime and minor corrosion, use an ammonia-based window cleaner.This is also important because a clean battery surface helps slow or stop corrosion on nearby metal. This is important, as you do not want any foreign material entering the battery cells when you open them. Before you check the water levels, clean any dirt or debris from the top of the battery and around the battery terminals.
